Catastrophe bonds and private insurance-linked securities (ILS) largely deliver returns based on insurance and reinsurance risk premiums, but in an environment where uncertainty suggests upside risks to inflation, specialist investment manager Leadenhall Capital Partners LLP has explained how this can play into ILS returns as well.
This has served to underscore the importance of diversification within investment portfolios, with catastrophe bonds and private ILS seen as one asset class that is largely remote from the risks posed by geopolitical shifts.
In a previous insight, specialist ILS manager Leadenhall Capital Partners had previously explained why catastrophe bonds and insurance-linked securities have been exhibiting significantly lower volatility in 2026, even under global stresses from conflicts and macro-economic concerns.
Now, the investment manager has also explained why heightened concerns over the trajectory of inflation is another macro factor where cat bonds and ILS can further display their diversification benefits.
“Recent geopolitical developments, including heightened uncertainty in the Middle East have contributed to renewed upside risks to global inflation. These pressures have translated into higher base rate expectations and an upward sloping yield curve,” Leadenhall Capital Partners wrote.
Adding that, “Cat bonds and Private ILS contracts typically compensate investors via floating rate cash returns (linked to base rates) together with a fixed risk spread that is ultimately funded by insurance and reinsurance premiums. As a result, ILS instruments tend to have a degree of positive yield sensitivity to inflationary environments.”
Beyond the potential for the fixed-rate floating return component of cat bond and ILS instruments to remain higher, there are a number of other factors where an inflationary environment can influence market performance and growth, Leadenhall Capital Partners highlights.
The investment manager states, “Higher rates support income: Heightened geopolitical uncertainty has increased inflation expectations, pushing base rates higher and yield curves steeper. This directly lifts the floating portion of ILS, increasing the running yields.
“Inflation drives the need for reinsurance: Rising replacement costs, labour and materials inflate insured values and nominal loss estimates, increasing required limits and the need for reinsurance, including private ILS and cat bonds.
“Structural repricing mitigates loss inflation: While inflation raises absolute loss sizes, the ILS market has demonstrated a strong ability to reprice risk and adjust attachment levels over time.”
On top of this the portfolio diversification benefit of cat bond and ILS investments remains strong and the fact it is insurance risk driving the largest return component means in an inflationary or uncertain environment, when other asset classes may be negatively affected, the ILS asset class continues to deliver for its investors.
Leadenhall Capital Partners explained, “his provides genuinely diversified and defensive yield during periods of macro uncertainty, geopolitical volatility and stress across financial markets, as reflected by the Swiss Re Cat Bond Index being up 1.89% year-to-date (source: Bloomberg, 31 Mar 2026), for example the recent concerns around private credit funds investing in the software industry.”
